Juraj Križanić wrote Gramatíčno izkâzanje ob rúskom jezíku (Граматично исказанје об руском језику "Grammatical overview of the Russian Language"). In this work he described in fact not the Russian language but a Common Slavonic language based on different Slavic languages, mostly on Russian and Chakavian Croatian. The author used it not only for this grammar, but also in other works, including the treatise Politika (1663–1666). According to an analysis of the Dutch Slavist Tom Ekman, 59% of the words used in Politika are of common Slavic descent, 10% come from Russian and Church Slavonic, 9% from Croatian and 2.5% from Polish. Sample (Romanized, original in Cyrillic): Iazika sowerszenost iest samo potrebno orudie k mudrosti, i iedwa ne stanowito iee zname. Czim kiu narod imaet izradney iazik, tim prigodnee i witwornee razprawlyaet remestwa i wsakije umitelyi i promisli. Obilie besedi i legota izgowora mnogo pomagaet na mudrich sowetow izobretenie i na wsakich mirnich i ratnich del leznee obwerszenie. Modern Ján Herkeľ Another early example of a zonal language for Slavs was Universalis Lingua Slavica ("Universal Slavic language" or "All-Slavic language"). It was created and published by the Slovak attorney Ján Herkeľ (1786–1853) in his work Elementa universalis linguae Slavicae in 1826. Unlike languages like Esperanto, it had no well-defined grammar and no vocabulary of its own. Like many other pan-Slavists in the 19th century, Herkeľ considered the Slavic languages dialects of a single Slavic language, and his book is mostly a comparative grammar of these dialects, in which he sometimes offered grammatical solutions explicitly characterized by him as "Universal Slavic". Although Herkeľ found Cyrillic more suitable for the Slavic languages, he nevertheless chose the Latin alphabet for his project, with the addition of a few Cyrillic letters: ч and ш for č and š (remarkably, for ž he preferred ƶ, although he explicitly did not exclude Cyrillic ж either), as well as x for h/ch. Near the end of his book, Herkeľ gave a few examples of his Stylus Universalis, applied to the "Pannonian" (Slovak) dialect: Za starego vieku byla jedna kralica, koja mala tri prelepije dievice: milicu, krasicu a mudricu; vse tri byle bogate, okrem bogatstva milica byla pokorna, krasica uctiva, a mudrica umena. "In olden times there was a queen who had three very beautiful girls: Kindness, Beauty, and Wisdom; all three were rich, in addition to being rich Kindness was humble, Beauty was polite, and Wisdom was wise."
